Thank you all for kind replies. I blow the sensor with air but cannot remove it. So I guess I should send my camera to a Nikon dealer to clean the sensor. But I wonder if this is a serious problem. If it is not a serious problem, I will do it when I have my camera regullar yearly maintainance, which is about 6 months later.



Regarding the image, I tried to upload it to the album here. But I noticed that there are two steps: 1. upload; 2. review and publish. I don't quite understand the second step. It appears to me that the step 2 will publish the image somewhere on this site. But I am afraid that it does not make sense to pulish a "nonsense" image here. With just step 1 I could not finish the upload. So I uploaded the image to another site but it does not show up correctly here. Can anyone tell me how can I put the image here?



Thanks,

Frank
